山区公路中小跨桥梁设计关键问题研究

Study on Key Problems in the Design of Small and Medium Span Bridge of Mountain Highway

为保证西部山区路网建设的顺利开展,需要对山区公路中小跨桥梁设计进行深入分析。论文从山区公路中小跨桥梁设计的特点及存在问题出发,论述了桥梁选型、上下部结构选择以及抗震方面的设计原则及优化措施,通过对工程实例分析,明确其设计要点。

In order to ensure the smooth development of road network construction in western mountainous areas, it is necessary to conduct in-depth analysis on the design of small and medium span Bridges in mountainous areas. This paper discusses the bridge type selection of top and bottom structure selection and the seismic design principle and optimization measures, through analyzing the engineering example, clear the design key points.
